- Overview
- Recommended Products
- Power-off holding: no coil power is required during holding.
- Electrical release: apply 24V DC, with red connected to positive and black to negative.
- Energy-conscious operation: power is consumed during energized release rather than continuously during holding.
- Compact size: 40 mm diameter and 30 mm height.
- Mounting options: rear M4 mounting holes and a central M6 hole.
- Magnetic gripping of suitable steel parts in automated handling systems.
- Workpiece positioning during assembly operations.
- Fixture holding with electrically controlled release.
- Use a workpiece with good magnetic permeability.
- Keep the contact surface flat and clean.
- Workpiece thickness greater than 5 mm is preferred.
- The contact area should exceed the magnet's holding face.
XH4030 Permanent Holding Electromagnet
Hold without power. Release with 24V DC.
The Landa XH4030 provides magnetic holding force when unpowered. Applying 24V DC with the correct polarity reduces magnetic attraction for controlled release. Its compact design is suitable for integration into industrial steel handling, positioning and fixture holding systems.
Key Benefits
How It Works
Power OFF — Hold: the permanent magnet maintains magnetic attraction without energizing the coil.
Power ON — Release: energizing the coil reduces attraction. Residual holding force is specified as no more than 500 gf at 24V DC.
Control requirement: 10% duty cycle, with each energized period less than 2 seconds. The release coil is not intended for continuous energization.

Typical Applications
Workpiece and Contact Requirements
Actual holding performance depends on material, thickness, surface condition, contact area and air gap.
The specified holding force is not a rated lifting capacity. Validate the complete system for the intended load, orientation, acceleration and release conditions.
Frequently Asked Questions
Does it require electricity to hold?
No. XH4030 provides magnetic holding force when unpowered.
Is attraction completely eliminated when energized?
The specification allows residual holding force of up to 500 gf at 24V DC. Account for this in the release mechanism.
Can the coil stay energized continuously?
No. Observe the 10% duty cycle and keep every ON period below 2 seconds.
